Mathematician Offers New Solution to a Fundamental Cosmic Paradox
A thermodynamic analysis of spacetime also points to an unexpected role for emergent dark energy and hints that…
Quantum Gravity May Be Far Less Quantum Than Physicists Expected
Physicists have long assumed that uniting quantum mechanics with gravity would require spacetime itself to behave quantum mechanically.…
Meet Sabrina Pasterski: Stephen Hawking cited her, NASA wanted her, but she chose physics
Most children dream of flying a plane. Sabrina Gonzalez Pasterski built one. By the time she was 14,…
Time may be an illusion derived from quantum entanglement
Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker…
Wormholes may enable time travel, astrophysicists find
A ring in space, at least on paper, can do something a black hole cannot. It can connect…
24,000-atom mini universe demonstrates time flow without a clock
What if time isn’t woven into the fabric of reality at all? A new experiment suggests that the…
One of the Largest Physics Surveys Ever Finds No One Agrees on Anything
Last summer, Nature conducted a survey asking physicists about some quantum hot takes. That venture revealed significantly disparate…
